Ontario building code 2018 code#

Tables 16A and 16B have been combined into a single Table, with Rule 10-614 providing specific conditions for selecting the size of bonding conductor or bonding jumper.Дў015 Code - AFCI protection required, with some exemptionsДў018 Code - exemptions tightened, application to existing circuits clarifiedД¬larification is now provided for AFCI protection of existing branch circuits that are extended due to renovations or additions. Objectives for solidly grounded, impedance grounded, and ungrounded systems are clearly specified at the beginning of the Section. Section 10 requirements have been reorganized into a more logical flow of requirements and significantly reduced in size. The term вЂњneutralвЂќ has been replaced with the more accurate term вЂњidentified conductorвЂќ. This requirement applies to all occupancy types.

New Subrule 4-028(2) now mandates that an identified conductor be installed at each manual or automatic control location.

As the number of devices increases, the cumulative current through the bonding system will become unacceptable. Many of these devices require power to operate, and where used in a simple switch loop, create a small current through the bonding conductor. Installation of identified conductor at control locationsДў015 Code - Two wire simple switch loop acceptableДў018 Code - Identified conductor required at every control locationД¬ontrol devices are increasingly used as an essential part of energy management systems. New requirements for POE have been added to the Code in the form of new Rules 16-300 through 16-350, and Table 60.Дў. Cable heating is a function of the power it carries and as such, installation and layout become critical factors in ensuring safe operation. POE is typically implemented as a 'structured' cable system, wherein cables are bundled together for extended lengths. Through these cables, power levels approaching 100 W are possible, along with simultaneously communications between devices and systems. POE (Power over Ethernet) has existed for many years however, recent revisions to IEEE standards for communications cables has opened the door to higher power applications for POE, such as room lighting.

Read more below about the top 15 changes to the code. Requirements for power over ethernet systems have been added to Section 16, and requirements for marinas, wharves, and similar facilities have been substantially updated and reorganized in Section 78. Section 10 has been updated, reorganized, and significantly reduced in length. Section 62 now requires ground fault circuit interrupter protection for heating devices and controls in proximity to tubs, sinks, and shower stalls. For example, Section 26 now mandates the use of tamper-resistant receptacles in additional areas where children may be present. This edition features important revisions to many sections. Now in its 24th edition, the 2018 Canadian Electrical Code, Part I includes a number of significant updates and changes to better help electrical workers in the safe maintenance of electrical equipment and create safer electrical installations.
